Interesting read. Raises some good points and some concerning potential outcomes from someone who knows there stuff.

You can find the study he is referring to here: https://www.pestsmart.org.au/final-repo ... ct-cyhv-3/

What he has failed to mention is that there were high mortalities in the control trials (i.e. non target species exposed to the same treatment just without the virus), that none of the non target species had lesions consistent with the virus and that when they tested the tissue samples from non target species none of them showed any sign of being infected.

That is not to say it is case closed and certainly I'd be interested in learning more about why so many of the silver perch died, but I wouldn't be surprised if the aquaculture bloke has some conflict of interest somewhere

It is a real catch 22 - pretty well everyone wants carp gone, or at least vastly reduced, but every option put forward seems to have risk attached.
I'm no expert so have to go by what information we are told - and there is always two sides of every story - but I have to put my faith in fisheries that the appropriate work is being done and the risks weighed up. It is still a way off before anything happens, so lets see what more comes out between now and then.

Work brought in a professor to prove we could work in 47 degree weather
Because the airconditioning wasn't working, at 1 of the meeting, he walked out
It was 22 degrees.
I'm not saying this is happening, in this case, but some will get the result that is required by the person paying the bills.

Perhaps. What it does point out though is the test results need to be consistent and repeatable. And that that the cause of high mortality in natives needs to be categorically confirmed before the decision is made to release the virus. There is no room for speculation.

I haven’t been following the research but I am pretty sure that is just one of a number of studies done into its effects on Australian natives. It also backs up what has been seen overseas in both lab studies and in the real world in virus infected waterways- that the virus unique to carp
